I have no clue as to the U number for this big un, but rest assured, it's BIG.I weighed the insulator alone and it's 3 pounds. Nice cinnamon and amber glazed cabletop with THOMAS incuse embossed upside down on the ear's corner side. No damage, chips or cracks, but there are some tiny surface scratches in isolated places but they do not detract or cause any issues. I have seen a lot of porcelain list and sell on ICON, but I don't ever recall seeing one of these big pieces of U mud? Displays mint. First mail to me.... $20 + $8.95 flat rate shipping in USA.It's cheaper that way. Canada and other countries, I'll have to calculate ship costs. Well, lots of folks have looked so I must have this a bit overpriced. How about $12+ shipping?
